Abstract: As an important means to achieve seamless global coverage, the integration of Air-Space-Ground-based wireless network is one of the important visions of future mobile communication. In this paper, the development history of ground wireless mobile and satellite communication is briefly reviewed, the necessity of network technology integrating space and ground is demonstrated, and the different levels of network integration development are defined for the first time. Finally, the prospect of the development of a future integrated network is proposed on three aspects including network architecture, key technology, and terminal.  
Keywords: integrated communication system; non terrestrial network (NTN); terrestrial network (TN); future wireless communication system
